). Write the answer in standard form.

​

Answer 1

To simplify (3a^2 + 1) - (4 + 2a^2),

we distribute the negative sign to each term inside the parentheses:

3a^2 - 4 + 1 - 2a^2.

Next, we combine like terms:

(3a^2 - 2a^2) + (1 - 4),

a^2 - 3.

So, the simplified expression in standard form is a^2 - 3.
